Do you believe the full moon brings out the emotions and other "madness" out of people?
I could go with this explanation as it is possible. I don't know if the animals also show different characteristics when the moon is full. Personally though, I feel good when there is full moon.The reason is all scientific...look at it this way ...your body is like the earth, 75% water..the moon controls the tides and what not of the ocean...and if the world/you is made of a lot of water then the moon will be able to control you as well as the earth!!!!
I'm glad you mentioned it! The physics geek in me cringes whenever people bring up "the moon affects the fluids in our bodies" theory. No offense to anyone on here, of course.It's the cumulative effect of the moon's gravity on massive bodies of water that causes tides. For example, it doesn't do anything to a bucket of water. Last night I did a few computations using Newton's law of gravity. At the moon's average distance from the earth, the force it exerts on a 150 lb object (such as a person) is approximately 0.00012 oz, which is probably less than the weight of a speck of feather down.
By the way, the moon's gravity doesn't have any special affinity for water. It's just that water is relatively easy to deform. A gentle breeze over a large expanse of water can create a wave, but it won't budge a rock.
To get back to mythology, it is probably a myth that Newton discovered gravity when he got hit on the head by an apple falling from a tree under which he was sitting.
